Description

A CNC milling machine processing device

technical field

The utility model belongs to the technical field of mechanical processing, in particular to a numerically controlled milling machine processing device.

Background technique

At present, there is often a kind of workpiece used in ordinary CNC lathe processing workpieces. The rod part is small and the head diameter is large and flat. Usually, a section of lathe chuck jaws is turned, so that the chuck jaws cannot be used when turning general workpieces. , it needs to be replaced with a set of normal chuck jaws, which increases the cost, or because the diameter is too small, the normal chuck jaws can only clamp workpieces with a diameter greater than 10mm, while workpieces with a diameter of less than 10mm cannot be clamped. It is necessary to replace the special chuck jaws; most of the instrument lathes and hand lathes use spring chucks for quick clamping, which is suitable for the processing of large batches of small parts, and for small blanks whose head size is larger than the size of the rod and the rod needs to be processed The workpiece cannot be clamped.

In order to solve the above problems, the Chinese patent with publication number CN102756291A discloses a kind of collet, which uses its shape as a straight cylinder, utilizes the elasticity of spring steel, and the radial force of chuck jaws or collets acts on The collet makes it clamp work, the chuck jaws or collets are relaxed, and the collet and the workpiece can be loaded and taken out together. For workpieces with small rods and large and flat head diameters, using this kind of spring collet can ensure the machining accuracy on the one hand, and reduce the cost on the other hand. Only workpieces with a diameter larger than 10mm can be clamped, and workpieces with a diameter smaller than 10mm can be turned by using the invention.

For another example, the Chinese patent whose publication number is CN202752642U discloses a kind of spring collet used for CNC lathe and hand lathe. The radial force of the collet acts on the collet to make it clamp, the chuck jaw or collet is loose, and the collet and the workpiece can be loaded and taken out together.

The technical solution above is designed for the CNC lathe that cannot clamp workpieces with a diameter of less than 10mm, although the spring collet can achieve the purpose of turning workpieces with a diameter of less than 10mm. But because the through hole of the clamping part of the spring collet is a straight hole, only the cutter with straight shank can be installed, and the cutter with taper can't be clamped.

Utility model content

The purpose of the utility model is to provide a CNC milling machine processing device for the shortcomings of the accessories of the CNC milling machine.

The utility model is realized through the following technical solutions.

A CNC milling machine processing device, comprising a spring jacket body and a screw, a cavity is arranged on the top of the spring jacket body, the screw is installed in the cavity, and a through hole communicating with the cavity is provided inside the spring jacket body , and the through hole is a tapered structure.

Washers are also sleeved on the screws.

Several through grooves are evenly arranged on the body of the spring collet along the circumferential direction.

The upper part of the spring collet body is also provided with an annular groove.

Four through grooves are evenly arranged on the body of the spring collet along the circumferential direction.

The taper of the through hole is Morse taper.

The taper of the through groove is consistent with the taper of the through hole.

The beneficial effects of the utility model are:

Compared with the prior art, the utility model sets the through hole in the body of the spring collet into a tapered structure, so as to meet the clamping requirements of the tool processing with a taper handle, and solves the problem on the CNC milling machine well. A tool with a tapered tool handle is installed, which overcomes the shortcomings of the existing straight-hole spring collet during use. The utility model has the advantages of simple structure, convenient use and better economic benefits, and can be widely applied and promoted in the mechanical processing technical field.

detailed description

The technical solution of the utility model is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

As shown in Fig. 1 to Fig. 3, a kind of CNC milling machine processing device described in the utility model comprises a spring collet body 3 and a screw 1, a cavity 31 is arranged on the top of the spring collet body 3, and the screw 1 is installed In the cavity 31 , the spring collet body 3 is further provided with a through hole 32 communicating with the cavity 31 , and the through hole 32 has a tapered structure. The technical scheme adopts a tapered through-hole structure, which is suitable for machining tools with a tapered tool handle, and overcomes the shortcomings of the existing straight-hole spring collet for clamping parts.

A washer 2 is also sleeved on the screw 1 . During processing, the washer 2 is installed between the screw 1 and the tool, the screw 1 is tightened, and the device is installed on the main shaft of the machine tool to process.

Several through grooves 33 are evenly arranged along the circumferential direction on the spring collet body 3 . The through groove 33 is provided in order to make the spring collet elastic, which is convenient for clamping and taking out the tool.
